FIFO的深度:指的是FIFO可以存储多少个N位的数据(如果宽度为N)。 满标志:FIFO已满或将要满时由FIFO的状态电路送出的一个信号,以阻止FIFO的写操作继续向FIFO中写数据而造成溢出(overflow)。 空标志:FIFO已空或将要空时由FIFO的状态电路送出的一个信号,以阻止FIFO的读操作继续从FIFO中读出数据而造成无效数据的读...

Bitmap是一种紧凑的数据结构,它使用一组连续的比特位(bits)来表示一组数据元素的状态或存在性。每个比特位对应一个特定的数据元素,值通常为0或1,表示该元素是否满足某种条件(如是否存在、是否已使用等)。由于比特是最小的存储单位,使用bitmap可以大大节省存储空间,特别适合处理大量整数型数据。
